In a Belfast courtroom Robert Rusting is on trial for the murder of his father, a former loyalist hardman. On the jury is James Fechner, a middle-aged surgeon in search of meaning in the hushed rooms of justice, inexplicably drawn to the younger man before him.

After trial, Fechner can't quite return to life before those days in court. In dingy pubs and rowdy boxing halls Fechner inserts himself into Rusting's world in another guise, following a compulsive pull to an aggressive, unapologetic way of life. So begins a close friendship, a relationship in which a battle for control is tacit but unspoken - and explosive.

Silverback is a powerful portrayal of the complications of masculinity and of the line between fragility and violence told in an unforgettable voice.
